Ok man here is the hlp
If you try to find the relationship between the unsaturated fat and drops of bromine u will find out that unsaturated fat=7*bromine wateer
So thereforre it is 56=7x which is equal to 8

I chose bromine water and unsaturated fat cause as you add bromine to unsaturated fat it turns colourless

Hope I helped!!!
Good luck :good:
